Description

本発明はリニアガイドウェイの潤滑システムに係り、特に潤滑油の潤滑経路を改善することにより、潤滑油が第一及び第二回流溝に平均に分け流し、且つ潤滑システムの密封性も向上できるリニアガイドウェイの潤滑システムに関する。
The present invention relates to a lubrication system for a linear guideway, and in particular, by improving the lubrication route of the lubrication oil, the lubrication oil can be divided into the first and second circulation grooves on the average, and the sealing performance of the lubrication system can be improved. The present invention relates to a guideway lubrication system.

一般の機械には直動機構が取り付けてある。リニアガイドウェイが直動機構の一つである。リニアガイドウェイは充分な潤滑油で転がり玉を潤滑することが必要である。そうすると、運行が正常になり且つ使用寿命を長く延ばすことができる。 A general machine is equipped with a linear motion mechanism. A linear guide way is one of the linear motion mechanisms. The linear guideway needs to lubricate the rolling balls with sufficient lubricating oil. Then, and service life operation becomes normal can long extension bus.

リニアガイドウェイの潤滑油の潤滑経路は、図１０に示すように、一般的には、エンドカバー６０の上に一つの注油孔６１を開けて、エンドカバー６０の組合面で所定の油路６２を設け、エンドカバー６０がスライドブロックの端面に合うと、潤滑油の潤滑経路が形成され、潤滑油が前記潤滑経路に沿ってエンドカバー６０の組合面で流動してエンドカバー６０の上下に形成された第一及び第二回流溝６３,６４に流入する。
また、製造コストを低減するために、一般的は、エンドカバーの組合面が一カバープレートに設計している。
また、前記カバープレートをエンドカバーに合わせると、転がり玉が回流する第一及び第二回流溝６３,６４が完成する。
この設計では、カバープレートの上には所定の油路が設けてあるので、潤滑油が案内されてエンドカバーの転がり玉が回流する第一及び第二回流溝６３,６４に注入する。
上記の二種類の方法では、潤滑油が同一の片平面に流動し、潤滑油が各転がり玉が回流する第一及び第二回流溝６３,６４内に平均に分け流すことが難しいので、転がり玉が回流する第一及び第二回流溝６３,６４内の転がり玉への潤滑が不平均になり易い。そのため、リニアガイドウェイの転がり玉の使用寿命にバラツキが生じ、全体の使用寿命が短くなる。
且つ潤滑油路がエンドカバーとスライドブロックとの接触面に露出するので、加工精度に誤差がある場合、又は、平面粗さが良くない場合には、潤滑油が前記接触面から漏れ出す。

In this design, since a predetermined oil passage is provided on the cover plate, the lubricating oil is guided and injected into the first and second circulation grooves 63 and 64 through which the rolling balls of the end cover circulate .
In the above two methods, the lubricating oil flows on the same single plane, and it is difficult to divide the lubricating oil into the first and second circulation grooves 63 and 64 through which each rolling ball circulates. Lubrication to the rolling balls in the first and second circulation grooves 63 and 64 through which the balls circulate tends to be uneven. Therefore, the service life of the rolling balls of the linear guideway varies, and the overall service life is shortened.
Since and the lubricating oil passage is exposed to the contact surface between the end cover and the slide block, if the machining accuracy is an error, or if poor plane roughness, lubricant leaking from the contact surface.

図１は本発明に係るリニアガイドウェイの潤滑システムの斜視図である。
スライドブロック１０の両端にはエンドカバー２０とカバープレート３０とがそれぞれ設けてある。
エンドカバー２０とカバープレート３０とを組み合うと、転がり玉を転向し回流させるための第一及び第二回流溝６３，６４が形成される。 FIG. 1 is a perspective view of a lubrication system for a linear guideway according to the present invention.
An end cover 20 and a cover plate 30 are provided at both ends of the slide block 10, respectively.
When the end cover 20 and the cover plate 30 are combined, first and second flow grooves 63 and 64 for turning and circulating the rolling balls are formed.

図２は図１におけるエンドカバーの斜視図であり、図３は図１におけるカバープレートの前側から見る斜視図であり、図４は図１におけるカバープレートの後側から見る斜視図である。
当該エンドカバー２０は二つの注油方向を有し、それは端面にある注油孔２１と、側面にある注油孔２４とである。
潤滑油が注油孔２１からカバープレート３０にあるオイル流し孔３１に注入するときに、仕切り具３５が潤滑油のスライドブロックの端面への流しを阻止する効果があるので、潤滑油は、第一案内油路３２により両側へ導かれて両側の第一通油孔３３に流入する。
さらに潤滑油は、カバープレート３０の反対面（エンドカバー２０との組合面）からカバープレート３０の正面の第二案内油路（その正面とスライドブロックとの組合面におけるより短い案内油路）に導かれて、第一回流溝６３と第二回流溝６４との中央位置にある第二案内油路（ほぼ螺旋孔２６の位置）が第二通油孔３４と連通していることにより、潤滑油がエンドカバー２０にあるオイル供給曲面２５に戻って第一回流溝６３と第二回流溝６４とに供給し、転がり玉が適正に潤滑される。
また、注油孔２４から潤滑油を注入する場合には、潤滑油は、オイル流し孔２３から第一案内油路２２に流入して注油孔２１に導かれ、上記と同様な流動経路を経て第一回流溝６３と第二回流溝６４とに別々に供給され、転がり玉が適正に潤滑される。 2 is a perspective view of the end cover in FIG. 1, FIG. 3 is a perspective view seen from the front side of the cover plate in FIG. 1, and FIG. 4 is a perspective view seen from the rear side of the cover plate in FIG.

When the lubricating oil is injected from the oil injection hole 21 into the oil flow hole 31 in the cover plate 30, the partition 35 has an effect of preventing the flow of the lubricating oil to the end face of the slide block . It is guided to both sides by the guide oil passage 32 and flows into the first oil passage holes 33 on both sides .
Furthermore, the lubricating oil flows from the opposite surface of the cover plate 30 (the combined surface with the end cover 20) to the second guide oil passage in the front of the cover plate 30 (the shorter guide oil passage in the combined surface of the front surface and the slide block). The second guide oil passage (substantially the position of the spiral hole 26) at the center position of the first circulation groove 63 and the second circulation groove 64 is guided and communicated with the second oil passage hole 34, thereby providing lubrication. Oil returns to the oil supply curved surface 25 in the end cover 20 and is supplied to the first circulation groove 63 and the second circulation groove 64, so that the rolling balls are properly lubricated.
Further, when the lubricating oil is injected from the oil injection hole 24, the lubricating oil flows into the first guide oil path 22 from the oil flow hole 23, is guided to the oil injection hole 21, and passes through the same flow path as described above.

A recess 352 and an annular convex edge 353 are included.
Since the thickness of the partition member 35 at the annular groove 351 is reduced and the strength thereof is weakened, when a force is applied to the conical recess 352 by the conical fitting 40, the portion surrounded by the annular groove 351 is easily removed from the cover plate 30. It can be separated and becomes a passage in the open state of the partition member 35.
Further, as shown in FIG. 9, an annular convex edge 353 is provided in order to enhance the sealing performance when the oil is injected from the oil supply hole 11 in the slide block. Then, the lubricating oil will not leak out.
